TROLLEY GUARD.

APPLICATION FILED APR.11. 1908.

.Patented @0%. 27, moa.

l Y y tion between the arms 18 and 20, a means is provided whereby theguard 'ame canbc maintained in a vertical position, irrespective of theangle in which the trollei7 pole extends and this provision is alsoobtained i owing to the manner in which the guard frame is connectedwith the arm 18, that is to say through the medium of a swivelly mountedring v13. If the connection were fixed between the guard frame and thearm 1S, it is evident that the guard frame could not be maintained in avertical position, irrespective oit' the varying angular positions ofthe trolley pole.

It is thought that the operation of the guard can be thoroughlyunderstood owing to its simplicity, but it will be stated that when theenlarged segment-shaped portions 9 meet with an obstruction or a switchon the wire, vthey will gradually cause, owing to their shape, thelowering of the'guard fra-me and readily pass the obstruction, and afterthe obstruction is passed owing to the expanding of the spring 14 theguard frame Will be returned to its normal position which is as clearlyshown in Figs. 1 and 2.

What I claim iz- 1. A trolley guard comprising a guard frame provided atone end with a segmentshaped enlargement, an adjustable supporting.means for said frame, and means Constr toting a swi.eled connectionbetween the frame and the supporting means.

2. A trolley guard comprising a guard frame provided at one end with asegmentshaped enlargementan adjustable supportin'g means for said frame,means constitut- ,ing a swiveled connection between the frame and thesupporting means, and a combined retaining and cushioning spring carriedby thefaxne'i and abutting against the swiveled ,connectio'n.

3. A trolley guard comprising a guard frame mounted upon the pivot ofthe trolley wheel and having its upper end projecting above the wheel,an adjustable supporting means for said frame, and ay swiveled coninection between the supporting means and the frame. I v
